Summary

In this chapter, we created our first functional application—something like a hello world example but with a bit more functionality close to the real world.

The essential part we covered in this chapter is to familiarize ourselves with the tools we will use. In later chapters, we will assume that these concepts are already clear. For example, we will move forward step-by-step when using SoapUI as this is a tool that will facilitate the task of testing the functionality that we will be developing. This way, we will avoid the task of writing code for web service clients.

Now we are ready to review the next chapter, which contains some security models that Java provides. We will understand each one of them and learn how to implement them.
